GYRATORY STRUCTURE.

To aZZ whom it may concern: 4 1

Be it known that I, .GEORGE W. CoMBs, a citizen of the United States, residing at- Leavenworth, in thecounty of Leavenworth and State'of Kansas, have invented certain new and useful Improvements in Gyratory Structures, ofwhich the following is a specification.

This invention relates to improvements in gyratory structures such as flour-sifters, etc. and my object is to overcome. excessive throw of the gyratory structure which is notonly detrimentalto the structure itself, but also to thebuilding containing the same.

This excessive throw. in flour-sifters is gen-' erally caused by one of the sieve-boxes be-'- coming overloaded with'stock and overbalancing its companion, and when the sifter the accompanying drawings, in which: Figure 1 represents a vertical section of has a rigid connection with the building, as

through its drive-shaft and a stationary bearing, considerable strain is imposed upon a gyratory structure-provided with my improvements. Fig. 2 shows the several parts of the inclined way restraining means in perspective, ready to be assembled. Fig. 3 is a broken vertical section of the lower end of the drive-shaft, the ,inclined way re-- straining means, a driver, a step-bearing for the driver, and the yielding coupling between the driver and the shaft. Fig. 4 is a broken vertical section on. line IV'-IV of Fig. 3. Fig. 5 shows the several-parts of the yielding coupling between the driver and theshaft, ready to be assembled. Fig.

6 is an elevation partly. in section of a modified form of sieve-structure provided with my driving and restraining mechanisms.

Fig. 7 is avertical section of a modified form of my drivmg and restraining mechanisms. Fig. 8 is a vertical sect on of the sieve-structure provided with another modified form of driving and restraining mechanisms. Fig. 9 is a vertical section'ofthe driving'mechanism shown n- F g. 8. Fig.-

10 is a side elevation partly in section of another modified form of restraining mechanism. v

l designates the sieve-structure, of any preferred type, which is suspended from above by flexible rods 2, and provided with centrally-disposed bearin s 3, in which the vertical drive-shaft 4 is ournaIed and has slight longitudinal movement. Said driveshaft is provided with cranks 4, to impart agyratory motion to the structure, and it may be made in one piece, as shown in Fig. 1, or it may be made in two or more pieces, as shown .in Figs. 7 and 8.'

The inclined waylrestraining means for restrictingabnormal'throw of the structure consists, preferably, of a plural-piece member 5 embracing a bottom piece 6, an intermediate piece 7 movable upon the bottom intermediate piece. All of these pieces have inclined; ways, which normally hold pieces and with the stationary bottom piece 6; Bottom piece 6 is connected to an adjacent portion of the building, as through a stubshaft 9 and a "step-bearing 10, Fig. 3, or through the means shown in Figs. 7 and 8, or it may be secured to the building by any other suitable means. Said bottom piece is provided with arallel inclined ways '11 and parallel incline'dg fways 12. Inclined Ways 12 are connectedi'npairs to form two V-shaped ways for the reception of'a pair of antifriction rollers '20, hereinafter re-' ferred to. Intermediate piece 7 is provided with parallel inclined ways 13 and arallel inclined ways 14, which latter are is osed at right angles to the former. Inc ined ways 13 are connected in pairs to form two inverted V-shaped ways adapted to travel to and fro upon the. inclined ways 11, said travel being limited by a hub 15 extending upwardly from the bottom'piece into the hollow portion 16 of the intermediate piece.

Top piece 8 is provided with parallel inclined ways-17 and parallel inclined ways '18, the former of which are adapted to travel to and fro upon the inclined ways 14 of the intermediate piece. Inclined ways 18 are connected in pairs to form inverted V-shaped ways which-travel upon a pair of antifriction rollers 21., hereinafter referred to, and the movement of the top piece is limited by an integral stop .19 depending.

into-opening 16 in the intermediate piece 7.

' piece, and a top piece 8 movable upon the -7 and 8 in axial alinement with each other e Qingcoupling consists of atop plate 29, an

' intermediate plate 30, and a bottomplate 31 i and yieldin-gly. connects the driver to shaft r that the wei ght By arranging the inclined ways 13 at right angles to the inclined ways 14 it is ap arent I latter ismovably mounted, upon the bottom that the movement of top piece'8 wil be at right angles to the movement of theintermediate piece 7, and when these movements occur simultaneouslythe top piece will, by reason thereof, be permitted to gyrate with the shaft. It is also apparent that when the intermediate and top pieces travel to and fro they will be. lifted by the inclined ways and raise shaft 4: and its weights, so of all of these parts acting on the inclined ways. will. tend to restore the intermediate piece 7' and the top piece. 8 to their normal positions, and through them restrict abnormal throw-,ofthe-shaft flandthe structure.

"of the. pieces 7- and weight of the V-shaped ways 14 and 18.

The gravity. of weight 8, together with the narily, .is sufficient to prevent them from moving too far, butas a matter of safety I provide the hub. 1.5 and stop 19- forthe purpose. of positively checking the movesv 'ments of said intermediate" and top pieces. To prevent undue Wear. of the plural piece member 5, I interpose the antifriction rollers 20. betweenthe' V-shaped ways 12 and 13,]and the rollers 21 betweenthe held from lateral movement. by the adjacent sidesof the intermediate piece 7 and-flanges 22," while: rollers 21 are held from lateral movement by the; adj acent sides of .the'intermediate. iece and flanges23, whichlat'ter depend fl om the adjacent sides of .thetop piece 8; 'Top piece 8 is .ievented from rocking on rollers 21 by a. all-beairing24,

. and. the intermediate piece 7 is prevented from rocking by the manner in which the rollers,.20 21 are disposed. Stub-shaft 9 is fixed at its lower end in step bearing 10,

. andits upper end is fixed in hub 15 to prevent the'p'luralrpiece member 5 from rotat-l ing' with drive-shafts. Said stub-shaft also forms the center:of. rotation around which I the drive-shaft. travels.

By arranging 29 will be permitted to move at right-angles to; the intermediate. plate.30, and when these plates move-simultaneously, the top plate will be. permitted towhich it? is connectedthrough an eccentric hub 37. As-it is desirableto have plates 29. and 30 operate with the leastpossiblefriction, so that no vibration will be trans- I mitted-fromthe gyratory structure to the ment relieves the. coupling of the weight of shaft. 4 andthe parts carried thereby;-

plate 29, which 'is'shown' inyerted in Fig. 5, is movable. on the intermediate. plate to. gyrate with the. shaft.

In order that the rotation of'shaft: 4 and but: little. friction, I secure the cone-38 of the 'ball-bearing,'.to the underside of; the top plate 29, andthecup .39 of'said ball-bearing to. the. upper surface of toppiece 8 of the plural-piecemember 5, plates. 30 and 31 of plied to the lowerend, of shaft 4 and to the eccentr chub 37 through an annular recess 41, which communicateswith aduct 42,

thronghan. orifice 43, with the top-plate 29, which has'a duct 44'leadingto a duct 15 in the cone 38', so that chamber 28 may be filled, or replenished with oil as occasion requires. Top piece 8 of the plural-piece meniber '5 "has a conical boss 46- extending up through cup 39, and the apex ofsaid bossis concentric with the duct 45, so, that when" the oil flowing through the latter falls upon the former t will 'be equally distributed thereby over the. working surfaces of the ball-bearing 90 building, I concave the top plate 29 so that itiwill-rest upon the ball-bearing 24 which in turn lSi supported by-the' plurahpiece meniher; 5, as-shown' in Fig. 3. This'arrangeits length, and in The inclined way restraining mechanism and the yielding coupling disclosed by Fig. 6, are duplicates of thoseshown in Fig. 3:, but the si'evestructure 1? may consists of a sin le sieve-box ora' pair of sieve-boxes rigidly connected together,-so that they'will operate as one unit. The shaft 4", which drives-the structure, is straight throughout shown in Fig. 1, it is provided with a pair of eccentric Weights 47, which, when the shaft is rotated, impart ayratory motion to the structure 1', the same eing suspended .from. the ceiling of the building by flexible Referring now to the modified form, Iiig. 7, 9 designates a stationary stub-shaft, which is .fixed in the lower portion of a stepbearing 10 secured to .an adjacentportionof the building, as the floor A- dGSlg" 'nates a driver journaled upon the stubshaft andprovided with a hub 26*, which extends down into said step-bearing andissupported thereby. The inclined way restraining means consists of a plural-piece member 5, comprising a bottom piece .6, anintermediate piece 7, and a top piece 8,

all of which are similar in form to the plural-piece member 5, except that the bot- .tom piece 6%. is secured to the floor by a spider 48, instead'of the stub-shaft 9, and

which is connected thereto byan eccentric hub 37%. Pin 50 is supported by the pluralfriction between saidipin and the top piece 8 I interpose a ball-bearing 24 between the same.- Pin 50 is connected to the driver "25 by a yielding coupling consisting of a,

One. advantage derived from the construction shown by Fig. 7 is that in 50-extends through the hub 49 and thusovercomes all tendency of the top piece 8- to rock upon the intermediate piece 7". A

further advantage is that the plural-piece lace .of the cranks 4?v member 5 andthe yielding coupling are spaced some distance apart,""so that access may be had to one ithout interfering with the-other. i Y

that it may moveup and down with the ini r pling and the drlver, and thus rotate the drive-shaft 4, I provide it with a feather 51, which extends through aregistering groove in thetop plate 29", in the" well known manner.- Driver 25 is journaled upon'a stub-shaft 9" andhas a .hub 26". ex

- tending down into and'supported' by a step bearingi throug 10". Pin 53 extends upwardly and is supported by-aplural-piece member 5, similar in construction to the plural-piece, member 5, disclosed by Fig. 2, with the exception that the bottompiece 6 lis secured to a frame 57, depending. from the ceiling of the building insteadof being supported by the'stu'b-shaft' 9. A ball-bearing 24 'is interposed between top piece 8" of the plural-piece "memberand the pin 53, 'which latter is provided with a pair of adjusting-nuts '58 at its upper end,, so that the cranks 4" of shaft 4 may be adjusted in-proper relation to bearings 3, by

adjusting said shaft up or down with the "nuts; Ball-bearing 24 f is protected from dust by a cap 59, resting upon theplural-J piece I member.

The modified form of the plural-piece I member shown by Fig. 10 isa duplicate of the one disclosed by Fig. 2, except thatthe.

inclined ways 12?, 13- are curved instead of being V-shaped' like th'e inclined ways 12 to 18, inclusive; The advantage. derived 'from the curved mclined ways resides in i usm the fact that therestraining influence of the plural-piece member upon the drive shaft increases in proportion to the lateral movement of pieces 7 and 8, whereas the resistremains the same irrespective of the extent From the above description it will be understood that I reserve the right to make fance offered by'the straight inclined ways, piece member 5 and the ball-bearing 24*" the inclined 'ways either straight or curved.

=1 also reserve the right to make such other changes in-the' details 5 of'cons'truction and r ality of incline angles to each other whereby abnormal restraining means in portingimeans consisting of a plurality'of' a other and tendingto hold the structure arrangement-of parts as properly fall with in the spiritand scope of the appended claims. 1
